PROBLEM TO BE SOLVED: To provide a scroll fluid machine reduced in size with a simple structure and usable as an efficient scroll blower. SOLUTION: The scroll fluid machine is equipped with: at least two drive scroll wraps of a spiral shape; and a disk-shaped driven scroll block formed with spiral movement spaces in which the drive scroll wraps are inserted and define compression spaces and a wall portion between the movement spaces serves a driven scroll wrap. The positions of outer peripheral side tips of the drive scroll wraps are set so that they contract with outer peripheral ends of the corresponding movement spaces of the driven scroll block in whirling motion of the drive scroll wraps relative to the driven scroll block when the respective drive scroll wraps whirl to a forward side in a rotation direction.
